But his attorneys say it was an accident. Court documents say Dapoltio told police he and his wife were sleeping on the bathroom floor after he had used cocaine and his wife had used Oxycontin when a gun he was holding went off. Dapolito said he panicked after the shooting.

Soon after, he said he used his brother's truck and stashed his wife's body at his father's house in Upton.

Prosecutors say the evidence tells a different story.

Police believe Dapolito was an abusive husband who used a gun to threaten Winslow and intentionally shot her in the head.

According to the affidavit, Dapolito was jealous before the shooting and accused his wife of being unfaithful.
